MyelinAndQuantum642

Gaps between segments of myelin sheaths (a) are small enough to consider the entire myelin-coated axon as a cylinder (b) with the axon’s radius as 𝑎, the entire cylinder’s radius as 𝑏, and the thickness of the myelin sheath as 𝑑=𝑏−𝑎. The length of the cylinder is denoted by 𝐿. (c) Phospholipid molecules in myelin have tails with a large number of carbon-hydrogen bonds. (Liu et al., Physical Review E, 2024)
